1. LAW OF ________________ is another name for Newton’s First Law.
Inertia
Gravity
Acceleration
Momentum
Newton’s first law says that an object that IS NOT MOVING, or is at ________, will stay at ________, AND an object that IS MOVING will keep moving with constant __________, which means at the same _______ and in the same ____________, UNLESS an ________________ force acts on that object.
rest; rest; velocity; speed; direction; unbalanced
motion; motion; acceleration; force; position; balanced
rest; motion; speed; direction; force; balanced
motion; rest; velocity; speed; direction; balanced
Inertia is the tendency of an object to:
remain at rest or in uniform motion unless acted upon by an external force
change its shape spontaneously
increase its mass over time
emit energy continuously
The property of an object that determines how much inertia it has is:
mass
volume
temperature
color
Which of the following has more inertia?
bowling ball
golf ball
One example where inertia can be observed in everyday life is:
A person continues moving forward when a car suddenly stops.
A plant growing towards sunlight.
A ball changing direction when hit by a bat.
A magnet attracting iron nails.
Newton’s second law says that when an ________________ force is applied to a ________________, it causes it to ____________________________.
unbalanced; mass; accelerate
balanced; object; stop
equal; body; rotate
constant; particle; decelerate
8. The greater the force that is applied, the ____________________ the acceleration.
greater
lesser
slower
constant
9. The lesser the force that is applied, the ____________________ the acceleration.
lesser
greater
constant
variable
If the same force is applied to an object with a large mass, it will have a ________________ acceleration.
smaller
greater
constant
zero
If the same force is applied to an object with a small mass, it will have ________________ acceleration.
greater
lesser
no
constant
The equation that is used to solve second law problems is F = ma. What do each of the variables mean?
F = force, m = mass, a = acceleration
F = friction, m = momentum, a = area
F = frequency, m = meter, a = ampere
F = force, m = meter, a = angle
The equation that is used to solve second law problems is F = ma. What unit of measurement must be used with each variable?
F = Newtons (N), m = kilograms (kg), a = meters per second squared (m/s^2)
F = Joules (J), m = grams (g), a = centimeters per second squared (cm/s^2)
F = Watts (W), m = milligrams (mg), a = kilometers per hour squared (km/h^2)
F = Pascals (Pa), m = pounds (lb), a = feet per second squared (ft/s^2)
